2 Claims.

Fig. 1 is a side elevation of a support for pipe hangers or the like embodying the present invention and showing the same in place on a beam;

Fig. 2 is a perspective view of a part of the support shown in Fig. 1; and

Fig. 3 is a perspective view of another part of the support.

The support is illustrated in Fig. 1 of the drawings as secured in place on a typical beam which has a web I and a flange I I. The support comprises a hook bolt l2 having a nut l3 and washer I4 thereon and a clamp part l5 through which the hook bolt passes. A combined clamping bolt and hanger rod it also forms a part of the support and has nuts [1 and I8 threaded on one end thereof.

The clamp part as best illustrated in Fig. 2 is made of a rectangular piece of heavy sheet metal centrally perforated and then bent to a U-shape on a radius forming a curve I9 of sufficient size to embrace the bolt or rod is. The perforate or cut-away part of the clamp i5 is shaped to provide an inclined edge conforming, as shown in Fig. l, to the incline on the inner side of the beam flange H. The opposite edge of the opening is provided with a step or shoulder 2| spaced in close proximity to the nut 18 in order to prevent rotation of the nut when it is assembled in the position shown in Fig. l.

The washer i4 is illustrated in Fig. 3 as having flanges 22 thereon to embrace the separate edges of the clamp part 15 which the washer overlies. This prevents spreading of the clamp and generally strengthens the structure though the flanges may be omitted. if desired.

The manner in which the support is assembled on a beam may be understood by reference to Fig. 1. When the hook bolt l2 has been passed through the clamp part l5, its hooked end is engaged over one edge of the beam flange and the clamp part drawn securely into place over the opposlteedge by tightening the nut :3 against the washer 14. The rod l6 may have been previously loosely assembled through the lower part of the clamp I5 with the nuts I! and i8 in place thereon and is advanced upwardly through the nut ill by turning of the rod itself until its upper end engages the hook bolt l2 to hold it in position against the bottom of the beam flange. The portion of the hook bolt l2 against which the rod engages may be flattened if desired to form a seat for the end of the rod 16 though this is not necessary. The nut I1 is then advanced upwardly on the rod l5 into engagement with the lower edge of the clamp part l5 thus locking the rod against rotation and providing a downwardly extending threaded end upon which any clamping or supporting devices for pipe or fixtures may be carried. The length of the rod l6 may, of course, be varied to suit the nature of the device to be supported.

The adjustability of the support to beams of different sizes is illustrated in Fig. 1 wherein a larger beam is shown in broken lines as embraced by the hooked end of the bolt l2 which may be extended any desired distance by adjustment of the nut 13 thereon. The device as herein illustrated is extremely simple and inexpensive to manufacture because it is made of standard threaded rods or bolts and a simple rectangular piece of metal shaped by inexpensive punch press operations. To save material, the washer i l may be cut from the center of this piece of metal prior to making the larger perforation therein.

The threaded end of the hook bolt l2 also provides a convenient supporting member in addition to the downwardly extending rod Hi. If the beam flange is disposed in a vertical rather than a horizontal plane as shown, the end of the hook bolt would depend vertically and could become the principal support for hangers or fixtures.

I claim:

1. A device for supporting pipe hangers and the like from a beam flange which comprises a hook-bolt adapted to engage with one edge of a flange, a hook part slidable axially on the bolt and adapted to engage with the opposite edge of the flange, nut means on the hook-bolt to urge the hook part toward the hook end of the bolt so as to grip the edges of the flange, said hook part comprising a U-shaped metal plate perforated at its bend to receive the hook bolt and permit movement of the bolt in a direction trans- Verse to its axis so as to provide an adjustable space between the bolt and an edge of said perforation for engagement with the flange edge, a threaded rod received within the bend of the U-shaped hooked part at right angles to the hook bolt, and a nut on said rod disposed Within said perforation and bridging the opposite sides of the U-shaped metal plate to permit tightening of said rod against the hook bolt.

2. A device for supporting pipe hangers and the like from a beam flange which comprises a hook-bolt adapted to engage with one edge of a flange, a hook part slidable axially on the bolt and engageable with the opposite edge of the flange, a nut threaded on the bolt to urge said hook part toward the hook end of the bolt so as to grip the edges of the flange, said hook part comprising a U-shaped metal plate perforated at its bend to receive the hook bolt and permit movement of the bolt in a, direction transverse to its axis so as to provide an adjustable space between the bolt and an edge of said perforation for engagement with the flange edge, the said References Cited in the file of this patent UNITED STATES PATENTS Number Name Date 763,987 Kriebel July 5, 1904 989,808 Rockwood Apr. 18, 1911 1,652,695 Barber Dec. 13, 1927 1,673,813 Edelmann June 19, 1928 1,737,214 Brown Nov. 26, 1929 2,470,991 Kindorf et a1 May 24, 1949
